C语言里面链表的具体形式是什么

以下是链表表示的栈实现：
//--Symbol.h
//--symbol.h - definitions/declarations for symbols used by other C Header files

#ifndef SYMBOL_H
#define SYMBOL_H

#define STACK_H
#define TRUE 1
#define OK 1
#define YES 1
#define FALSE 0
#define ERROR 0
#define NO 0
#define OVERFLOW -1
#ifndef NULL
#define NULL 0
#endif

typedef unsigned int UINT;
typedef int STATUS;
typedef int BOOL;

#endif /*SYMBOL_H*/

//--stack.h - definitions/declarations for stack operation

#ifndef STACK_H
#define STACK_H

#include "Symbol.h"
#include <malloc.h>
#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
#include <string.h>

#define S_CHAR 1
#define S_SHORT 2
#define S_INT 3
#define S_FLOAT 4
#define S_DOUBLE 5

//-- Stack.h
typedef struct tagNode
{
